Now, the guys at MotorAuthority are reporting an early 2010 launch. The M3 CSL will replace many of the original M3's parts with carbon fiber and carbon fiber reinforced plastic in order to reduce the weight by at least 200 lbs.

Many other changes separate the CSL from the regular M3, things such as a fully reworked suspension, a 50hp increase to nearly 470hp, and stickier tires on special wheels all combine to offer real-world performance improvements. The expected price is around the $140,000 mark.

The 2010 BMW M3 CSL is expected to go from 0-60mph in 4.5 seconds, with a top speed of 186mph.
